 Here are the last lines from the last run that I closed down deliberately:

 May 08 21:20:37.000 [notice] Bootstrapped 100%: Done
 May 08 21:20:37.000 [notice] Now checking whether ORPort 71.126.229.56:443
 is
 reachable... (this may take up to 20 minutes -- look for log messages
 indicating success)
 May 08 21:20:38.000 [warn] Failure from drain_fd: No error
 May 08 21:20:38.000 [notice] Self-testing indicates your ORPort is
 reachable
 from the outside. Excellent. Publishing server descriptor.
 May 08 21:20:40.000 [notice] New control connection opened from 127.0.0.1.
 May 08 21:20:40.000 [notice] New control connection opened from 127.0.0.1.
 May 08 21:20:41.000 [notice] Performing bandwidth self-test...done.
 May 08 21:27:27.000 [notice] Owning controller connection has closed --
 exiting now.
 May 08 21:27:27.000 [notice] Catching signal TERM, exiting cleanly.

 Over many runs there has been no [warn] associated with the shutdown.  The
 warning "Failure from drain_fd: No error" shown seven lines above the
 shutdown appears that close only because I shut down after it happened to
 appear - in longer runs it occurs way before the shutdown.
 The notice "Owning controller connection has closed -- exiting now" has
 some
 variations in other logs:

 May 08 16:22:47.000 [notice] Monitored process 4128 is dead.
 May 08 16:22:47.000 [notice] Owning controller process has vanished --
 exiting now.

 I hoped to catch the PID (I presume of firefox.exe or tor.exe) in this
 last
 run, but I got the variant shown first above.

 The last notice "Catching signal TERM, exiting cleanly" always appears.
 HTH, eliaz
